Causes and control methods of pumpkin cracking

Pumpkin is one of the common fruits and vegetables, which tastes sweet and is deeply loved by the public, but pumpkin cracking occurs in both young and mature pumpkins, which seriously affects the quality of pumpkins and brings economic losses to farmers. So how to prevent and cure pumpkin crack? Let's take a look.

1. Occurrence of symptoms

Pumpkin crack will produce longitudinal, horizontal or oblique cracks on the melon surface, the crack depth, width and width are different, the serious crack can be as deep as the flesh of the melon, expose the internal seeds, and the fruit wound will be corked with the passage of time. There is only a small crack in the slight crack, but if the young fruit continues to grow after the fruit is cracked, then the crack will gradually deepen and enlarge as the fruit grows.

2. The cause

The main reason is that due to long-term drought or excessive water control due to disease prevention, and then sudden heavy rain or pouring water, the pulp cells absorb a lot of water and expand. However, the pericarp cells aged and could not grow synchronously with the pulp cells, resulting in pericarp cracking. In addition, when the young fruit is subjected to agricultural activities, the wound or mechanical wound will crack at the center of the wound when the fruit expands. The lack of calcium during flowering and the lack of calcium in the floral organ will also lead to the cracking of young fruit.

3. Prevention and control methods

The plots with flat terrain, loose and fertile soil and strong water and fertility conservation should be selected for planting. Before planting, the soil should be carefully prepared, fully mature organic fertilizer should be applied, and attention should be paid to the matching use of nitrogen, phosphorus and potassium fertilizer. Spraying calcium fertilizer before flowering can prevent plant calcium deficiency, reasonably water the soil during the growing period, and avoid soil drought or excessive wetness, especially pay attention to sudden rainfall or flooding after a long drought. When planting in the shed, we should pay attention to avoid high temperature or low temperature, in order to maintain the temperature of 18-25 degrees, agricultural operation must prevent mechanical damage.
